The SHR/SCR pathway directly activates genes involved in asymmetric cell division in the Arabidopsis root

Asymmetric division of cortex/endodermal initials (CEI) in the Arabidopsis root generates two layers of ground tissue and is controlled by a finely orchestrated interplay between the transcription factors, SHORT ROOT (SHR) and SCARECROW (SCR). To understand the dynamics of the SHR/SCR regulatory network we performed microarray time course experiments using inducible versions of SHR and SCR and examined their transcriptional effects specifically in the ground tissue.
